I'm looking for a circular saw. There are just so many to choose from. The primary purpose will be to cut down sheet goods using a straight edge. I considered the Festool system but it's just too expensive. I already have an 8' and 4' quick clamp. I intend to buy the plate that mounts to the saw and slides on the straight edge (Festool wanna be ). The saw is the problem. I considered the PC 4 1/2" saw but again, the sucker is expensive. I would like it to light and powerful enough to cut though 3/4" stock. Any suggestions would be appreciated.
